In each kind of device, the process stick to a process. A tube is packed into a bender which is held into place between two passes away. Technical power is used to force the tube against a die which causes it to comply with the appearance of the information. This is often done by spinning or moving its end around it (die).The process above is used in the different sessions of benders listed below. Each bender kind is different in the way it is applicable mechanical power to get the curvature.

Probably the most primary form of bender is the media bender. As the name indicates, mechanical power makes the curvature by pushing the tube against a die. The power is usually used hydraulically or pneumatically, with regards to the settings of it. This form of bender can be used on freezing tube joints but it usually deforms the combination area at the curvature to an square appearance due to the deficit of inner assistance.
